Half life is the time interval in which the number of nuclei present at at a given time decay(or disintegrate) to half of its value.

half life of hydrogen is 12.33 years,half life of cadmium is 5.1 X 10 raise to power 14 years,etc.

Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?

no, halflife is a constant for each isotope's decay process.

How do scientists use the halflife of radioactive isotopes to date rocks and fossils?

The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.

Can a sample of matter change its composition or state?

For chemical reactions, the elements in a sealed vessel will not change. But, reactions can take place that would tend to take the sample to a state of equilibrium. Or, with heating or cooling the physical state can be changed.Another type of reaction is nuclear decay, in which radioactive substances will spontaneously decay to other radioactive substances, or decay to non-radioactive substances, thus actually changing the elements present.


What is the difference between Chemical kinetics vs Chemical decay?

Chemical decay, also known as radioactive decay, is a process that occurs naturally (usually in isotopes or unstable substances) Chemical Kinetics is one of the ways you can analyze radioactive decay. Although it should be noted that radioactive decay undergoes first order decay when using Chemical Kinetics.
